摘要
工具振幅是功率超声加工中的一个重要参数,对加工过程及加工效果都有着重要影响。简述目前常用的振幅测量方法与原理,分析其优缺点。给出利用显微镜观察法测量超声加工工具振幅及在线检测频率变化的简易方法。
The vibration amplitude of the tool is one of the very important parameters in the power ultrasonic process, which has a crucial influence on the course and result of the processing. The usual methods and principles to measure the amplitude of mechanical vibration of tool were presented, and their advantages and disadvantages were discussed. An easy method was proposed to detect the tool amplitude of ultrasonic vibration by use of a reading microscope, monitoring the altering of frequency on-line.
